Re: Turning off telemetry channels with MTT4B?


 

If you post the MTT4 config, it would help.
Why are some packets on aprs.fi showing:
???? 2023-08-17 14:34:23 EDT: >APTT4,WIDE2-2,qAR,:!3556.54N108643.72W#PHG2547/EM65?de?WA4SCA

While others show:

Are you switching between 2 banks?? Or are there 2 devices running with the same CALLSIGN and SSID=0?
In one case, the packet is sent as text (uncompressed), and the second case, it is sent in Mic-E format
